Diverse populations make rational collective decisions

Understanding how ant colonies make collective decisions could provide insight into the functioning of the human brain. Yes/no binary decisions by individual ants can lead to a rational decision as…

Microrobots inspired by nature

A revolutionary design mimics the rowing action of the cilia on single-celled Paramecium, demonstrating much faster movement than conventional microrobots. Researchers based at South Korea’s Daegu Gyeongbuk Institute of Science…

Clues as to why cockroaches are so prolific

Asexual reproduction increases when female cockroaches are housed as a group, not alone, enabling them to maintain a colony for at least three years without a male’s contribution. Asexual reproduction…

Microbiome diversity is influenced by chance encounters

Study finds a role for randomness in the composition of the gut’s microbe populations. CAMBRIDGE, MA– Within the human digestive tract, there are trillions of bacteria, and these communities contain…

Watching gene editing at work to develop precision therapies

University of Wisconsin–Madison engineers have developed methods to observe gene editing in action, and they’re putting those capabilities to work to improve genetic engineering techniques. “Ultimately, the knowledge we gain…

A step closer to safe stem cell therapies

Stem cells derived from adult cells, called human induced pluripotent stem cells (hiPSCs), have great potential for basic research and regeneration therapies. But for clinical samples to be safe, these…

Sticking to the story at the molecular level

Molecular insight into protein net charge may explain and help solve the harmful build-up of organisms in the marine environment. A deeper understanding of protein adhesion to solid surfaces may…

Researchers Uncover Mechanism for Cancer-Killing Properties of Pepper Plant

UT Southwestern Medical Center scientists have uncovered the chemical process behind anti-cancer properties of a spicy Indian pepper plant called the long pepper, whose suspected medicinal properties date back thousands…

Live Cell Imaging Using a Smartphone

A recent study from Uppsala University shows how smartphones can be used to make movies of living cells, without the need for expensive equipment. The study is published in the…

Artificial Leaf as Mini-Factory for Drugs

To produce drugs sustainably and cheaply, anywhere you want. Whether in the middle of the jungle or even on Mars. A ‘mini-factory‘ whereby sunlight can be captured to make chemical…
